In `the accompanying drawings, Figure 1 is a top View of a railway-car having my invention attached thereto. Fig. 2 is a side elevation of Fig. 1.

Reftrrin g to the parts by letters, letter A represents the end of an ordinary railway freightcar; B, an ordinary draw-head, and O an ordinary coupling-link. D is aA rock-shaft, journaled in standards d on top of the car A, and some distance hack from the end of the car. E is a hand-lever attached to one end of the rock-shaft D. -F is a'segmental bar, mounted l on the car-top, and passes through a slot in the rbar E, and is pierced with holes f, in`

which a detent ou athumb-lever, G, engages to adjust it at different positions thereon. H is-an arm projecting forward from the rockshat't D. I is the coupling-pin extended in length so that its upper end may he hinged to Y the outer end of the arm H. The couplingpin has a collar, '5,' to limit its downward motion. The brakeman may, standing in a coinparatively'sat'e position, use the lever E to raise and lower the coupling-pin at will, and

drawn therefrom, and when in a third position the coupling-pin will be held clear above the draw-head, so that the cars may come together without coupling, substantiallyr as set forth. JOHN WAGNER. Witnesses: J. J. TUNNICLIFF,
